The events of the action film Black Site Delta take place on the territory of an ordinary prison. Prisoners serve their sentence, while overseers are closely watching over them. However, the armed bandits make an unexpected attack on the prison zone soon. The target of the militants are not criminals, they do not even think to free anyone. The thing is that the zone is a cover for a secret control point. The attackers can establish control over military unmanned aerial vehicles from this place.
The criminal grouping struck at the very “heart” of the state defense system. The military personnel do not stand a chance to free the Black Site Delta by own forces. The last opportunity of saving the Black Site is a group of prisoners. Military officials promise to get them out, regardless of what crime they committed in a past life. They have to warn the future capture of the building. The state gets back the territory of Black Site Delta, and the prisoners get eternal freedom.
